Vets have issued warning for dog owners following a surge in toxic blue green algae reports.

The British Veterinary Association (BVA) is urging pet owners to take extra precautions when walking their dogs in the vicinity of water bodies, after a spike in reports of toxic blue green algae in several locations across the UK.

Blue green algae or cyanobacteria are a group of bacteria that can contain dangerous toxins which can be harmful and even fatal to our pets, livestock and birds if ingested even in small quantities.

The warning comes as at least one case of a dog death linked to blue green algae exposure was reported in the Scottish Highlands.

Blue green algae blooms may appear as green or greenish-brown scum on the surface of water.

Dogs can swallow it by drinking water from an affected lake, river or pond or while licking their fur after going for a swim.

Symptoms of exposure can appear within a few minutes or hours, depending on the type of toxin ingested, and commonly include: vomiting, diarrhoea, drooling, disorientation, trouble breathing, seizures and blood in faeces.

If left untreated, it can cause liver damage and ultimately be rapidly fatal.

British Veterinary Association Senior Vice President Daniella Dos Santos said: “It’s been a warm start to the summer and we have started hearing of increasing numbers of blue-green algae sightings across the UK.

"While a paddle in a cool lake may be your dog’s favourite outdoor activity at this time of the year, we’d urge pet owners to keep them on a lead during walks near water bodies confirmed to have algal blooms.

"The majority of blooms are toxic and it is impossible to tell the difference visually, so it is better to be safe than sorry.

“There is currently no known antidote for the toxins, so prompt veterinary treatment is the only way to tackle their effects and ensure a good chance of recovery for your pet.

"If you suspect your dog has been exposed to blue-green algae, please seek emergency veterinary treatment as soon as possible."

BVA has issued the following advice for pet owners:

  • Look out for any warning signs put up by the Environment Agency or local councils near water bodies
  • Keep pets on a lead and by your side around water bodies known or suspected to have blue-green algal bloom – don’t let them swim in it or drink from it
  • If your dog has been swimming outside, wash it thoroughly with clean water afterwards
  • Seek emergency veterinary treatment in case you’re concerned it may have ingested toxic algae
